Abstract

Previous studies have preliminarily validated the floating reference method and shown that it has the
potential to improve the accuracy of non-invasive blood glucose sensing by Near-Infrared Spectroscopy.
In order to make this method practical, it is necessary to precisely verify and measure the existence and
variation features of the positional floating reference point. In this talk, a device which can precisely
verify and measure the positional floating reference point is built. Since the light intensity of diffuse
reflectance from the tested sample is very weak, a multipath detecting fibers system was built to
improve signal-to-noise ratio. In this system, the fibers encircle the light source fiber which is regarded
as the reference center of detecting fibers while they are moving. In addition, the position of each fiber
is accurately controlled by manual translation stage to keep all detecting fibers always in the same
radius around light source fiber. This ensures that received signal is coming from the same radial
distance of light source. The variation of signal-to-noise ratio along with the different radial distance
was investigated based on experiments. Results show that the application of this device could improve
signal-to-noise ratio, and provide a new experimental method for the further study of positional floating
reference point.
